Segment Reporting [Abstract] |
Segment Information | 4. Segment Information The Company follows the guidance prescribed by the Accounting Standard Codification (“ASC”) Topic 280, Segment Reporting, which governs the way the Company reports information about its operating segments. Management has organized the Company around its continuing products and services and has two reportable segments: Technical Products and Services (“TP&S”) and Electrical and Instrumentation Construction (“E&I”). TP&S develops, manufactures, provides and markets switchgear and variable speed drives. The service component of this segment includes retrofitting equipment upgrades, startups, testing and troubleshooting electrical substations, switchgear, drives and control systems. The E&I segment installs electrical equipment for the energy, industrial, marine and commercial markets. The American Access Technologies (AAT) segment manufactures and markets zone cabling and formed metal products of varying designs. Because of the disposition of the (AAT) segment’s operations and net assets in August 2014, that segment’s results are excluded from segment reporting and presented as discontinued operations in the accompanying condensed consolidated statements of operations. The following are selected financial details regarding the Company’s reportable segments (in thousands):
